Description

Artificial turf reproduction apparatus {AN APPARATUS FOR RENEWAL OF ARTIFICIAL TURF}

The present invention relates to an apparatus for regenerating used artificial turf used for a predetermined period in artificial turf, in particular, artificial turf for a sports field (playground) into artificial turf having characteristics and appearance similar to that of the initial stage of installation. Specifically, the present invention can suck the filler including the roller-shaped primary brush in the form of a needle, a secondary brush in synthetic resin (plastic) material, silica sand and elastic rubber chip and the addition of pile by air vortex At the end of its life, it includes a suction machine to allow for manual raising, a storage tank to store fillers including sucked silica sand and rubber chips, and a pile shearing machine to cut damaged artificial grass piles. The present invention relates to an artificial turf regeneration apparatus that may further include a hot melt plate capable of melting artificial turf files.

Artificial turf is a product made of artificial material that mimics the shape, use, and characteristics of natural grass. It is divided into household, public, and sports, and was developed to overcome the problems of free use and management of natural grass. Product. In general, the quality of artificial turf for athletic fields is measured by resilience, resilience, shock absorption, etc., and the interaction between athlete and artificial turf surface, the interaction between ball and artificial turf surface, artificial turf surface itself. The quality may vary depending on the characteristics. In order to secure the optimum performance of the artificial turf for sports grounds, about 60 to 80% of the turf pile height is filled with fillers such as silica sand and rubber chips, and the remaining about 20 to 40% is left free. The pile corresponding to about 20 to 40% of the total pile height of the artificial grass thus left is called a free pile height.

In general, in the case of artificial turf, the pile yarn of the free pile height part shows wear, cracking, twisting, and compression due to repeated static and dynamic loads over time after installation. Although the period in which the phenomenon is manifested differs depending on the frequency of use of the athletic field (regime field), it is generally changed to artificial turf in which initial performance and athlete stability are not guaranteed after two to three years. The phenomenon of being poor is expressed. In addition, since the material of the pile yarn is a synthetic chemical material, it is common to give a product warranty of about 5 to 8 years in the art due to aging of the material by ultraviolet rays.

The artificial turf pile is at the end of its life when the artificial pile pile of the free pile hight shows wear, cracking, twisting, and compression, and the fragments of the pile yarn are scattered. geotinde, search such artificial grass and it is general that the demolition waste, and thus mass production of a large amount of industrial waste (e. g., in the case of a normal soccer field has 8,000M ^2/1 if the production of waste × 35~40Kg / M ² This is very unreasonable in terms of efficient use of resources.

Meanwhile, as general laying equipment used for laying artificial turf on the first playground, equipment for filling and filling silica sand and elastic rubber chips into a certain layer between artificial turf piles for commercial performance is commercialized and sold. In addition, a device for cleaning the material of the running track, a suction device such as an elastic rubber chip, and the like are commercially available and sold. However, these equipments are irrelevant to the implementation of a new concept of eco-friendly artificial turf by the groundbreaking suppression of artificial turf waste and the efficient use of resources.

Therefore, the inventors, after diligently researching, an apparatus for regenerating used artificial turf used for a predetermined period in artificial turf, in particular, artificial turf for a sports field (playground) to artificial turf having characteristics and appearance similar to the artificial turf at the initial stage of installation. Invented.

The present invention can solve problems such as deterioration of performance and deterioration of quality, which inevitably occurred after the initial installation of artificial turf, and in particular, reduce the cost of dismantling and replacing waste artificial turf and improve the efficient use of resources. Therefore, an object of the present invention is to provide an artificial turf regeneration apparatus capable of realizing eco-friendly artificial turf different from the eco-friendly characteristics of the material itself constituting the artificial turf finished product module.

At about five years after the artificial turf was placed on the playground, the artificial turf was regenerated by the following method using the artificial turf regeneration apparatus of the present invention.

First, a separate device was used to inhale filler including silica sand and elastic rubber chips (eg EPDM). Subsequently, by using a roller-shaped primary brush (the material of the primary brush is steel) and a plate-shaped secondary brush of plastic (plastic) material with a plurality of holes, artificial grass pile ( In particular, the pile of a free pile height part) was raised to provide sufficient uprightness of the pile. The inhaler was then used to allow for additional raising of the pile by the vortex of air. Subsequently, the conventional filler was removed and the artificial turf was washed using a separate high pressure sprayer. The end-of-life pile was then melted by a hot melt plate, and then the damaged pile including the pile melted by the hot melt plate was cut by a pile cutter. The filler was then redistributed, including silica sand and elastic rubber chips (eg EPDM) stored in storage tanks.

The artificial turf thus regenerated showed similar appearance and characteristics (restoration, resilience, shock absorption, etc.) at the time of initial laying.

Fig. 1 shows the configuration of the artificial turf reproducing apparatus of the present invention.
